Unix is a much tougher case - while there have been a couple of viruses, they don't spread very well, even when everyone uses the same binary formats. B2 helps, of course; B1 configured reasonably should also work.
Most people are very nervous about running binaries on a unix box that they get off the net, and nobody runs a setuid-to-root binary on their system unless they paid $$$ for it and got it from a reputable vendor. I personally only run one binary on my machine that I didn't compile myself - that's Netscape. -- Ed Carp, N7EKG Ed.Carp@linux.org, ecarp@netcom.com 214/993-3935 voicemail/digital pager 800/558-3408 SkyPager Finger ecarp@netcom.com for PGP 2.5 public key an88744@anon.penet.fi "Past the wounds of childhood, past the fallen dreams and the broken families, through the hurt and the loss and the agony only the night ever hears, is a waiting soul. Patient, permanent, abundant, it opens its infinite heart and asks only one thing of you ... 'Remember who it is you really are.'" -- "Losing Your Mind", Karen Alexander and Rick Boyes
